Delicious and quick/ easy tray bakes please

[Hmmalittlefishy]

Hi
I need to bake for a school bake sale and would love some tried and tested tasty recipes.
I think cupcakes will be too fiddly. So was thinking of a tray bake if anyone is willing to share the recipe for their guaranteed successes
Thanks you

Google Mary Berry's lemon drizzle traybake. It is luscious.

Ohh I've made that before!!
But had completely forgotten you're right it is delicious - thank you

I think the pressure has got to me!!
